Title: Comminuting of thermoplastic fibre materials for recycling - by using thermoplastic properties e.g. heat fusing and cutting or cutting with hot blades, to form more compact raw material for melting down
Inventor: SIEBERT MARTIN DIPL ING
IPC: B29B13/10
Filed: 1992-02-02
Abstract: Process for comminuting thermoplastics fibre and prods. of these such as ropes, tapes, fabrics and fibre composites, to raise the apparent density and as preliminary step in their by recycling by melting down is claimed. The process is carried out making use of the thermoplastic nature of the fibres. Pref. the fibre raw material are heated by convection, conduction, infra red radiation or inductive heating until the individual fibres fuse together so that the prod. can be comminuted in conventional cutting mills and waste prod. cutters, or the fibre material may be comminuted by cutting using cutters with heated blades. USE/ADVANTAGE - The pre-processed fibre material is more compact, easier to handle, cheaper to transport and more convenient to use for recycling by melting.
Patent DE-4205139-A1 (DE)
Title: Controlling pneumatic or hydraulic fluid driven power switches - recharging fluid reservoir after switching off to allow further switch on and a further switch off
Inventor: FICK HANS ING GRAD
IPC: H01H33/30
Filed: 1992-02-20
Abstract: The method is applied to control hydraulic or pneumatic actuators with a fluid reservoir for power switches. The fully charged reservoir has a volume sufficient to provide a complete off-on-off (OCO) cycle. Switching off all or several switches takes out the switch-off energy from the fully charged reservoir capable of one off-on-off cycle. After switching off, the reservoir is first compulsorily recharged if the reservoir pressure has reached or come close to a value at which an on and off switching is still possible. USE/ADVANTAGE - Esp. for high and mid voltage applications. Gives priority to switching several switches back on after switching off and to shorten switching on process.
Patent DE-4206447-A1 (DE)
Inventor: SAUL HANS-PETER DIPL ING
IPC: B29C45/78
Filed: 1992-02-27
Abstract: A process for the clock-actuated injection moulding of a cross-linkable compound, especially one with low heat conductivity, in which, in a first phase of the working cycle, the compound is alternately fed in and, before its entry into the mould cavity or a runner leading thereto, is heated by a heating device and, in a second phase, cross-linked under the effect of an optimum temperature and then removed from the mould cavity. As the heating device passes through the successive partial quantities of the compound, a rise in temperature takes place up to a temperature producing, specifically to the mixture, substantial cross-linking within the period of the working cycle by the alteration of the quantity of heat applied to each partial volume corresponding to a preset or calculated profile and taking account of the differing paths followed by successively conveyed partial quantities of the compound to their final positions within the mould cavity and the time needed therefor in such a way that substantially even cross-linking takes place in these different partial quantities.

Title: Fibre feed for open end spinning rotor - has auxiliary suction duct in opening roller housing to remove entrained and broken fibres
Inventor: BILLNER WERNER
IPC: D01H4/34
Filed: 1992-08-17
Abstract: Sliver (1) is opened in an open end spinner by an opening roller (2) and transported pneumatically through a feed channel (5) to the fibre collecting surface of a rotor (40). Independently of the fibre feed, air entrained in the opening roller is drawn off from the opening roller housing (21) in a nominally fibre free region. This auxiliary air stream is strong enough to remove entrained fibres and fibre fragments. Also claimed is an arrangement where the auxiliary channel (7) is connected to a low pressure source independently of the fibre feed channel (5). Pref. the auxiliary channel (7) is taken to the rotor (40) to join the main fibre feed and ends up in a common feed slot. Alternatively the fibres collected can be taken to waste. The entry (7) to the auxiliary channel (7) is at an angle in the direction of rotation of the opening roller (20) and the channel tapers towards the rotor (40). USE/ADVANTAGE - Improved feed arrangement for open end spinning, especially with small rotors. The auxiliary channel ensures that there is no fibre build up in the opening roller housing which could suddenly be released and cause yarn irregularities.

Title: Drag reduction for boat hull - involves air inlets above waterline feeding air outlets below waterline to form air layer over hull
Inventor: LOHER JOSEF
IPC: B63B1/38
Filed: 1992-10-27
Abstract: The front of the hull (1) shape has air inlets leading to a pattern of outlet holes (6) spaced over the hull to form a carpet of bubbles between the hull and the water. The hole pattern is symmetric to the keel line to spread the air bubbles evenly. The airflow is provided by the ram effect of the motion of the boat and can be enhanced by a turbine inside the hull, and the suction effect of the water-flow past the hull. USE/ADVANTAGE - The air carpet is applied to that part of the speedboat hull touching the water at speed and reduces drag considerably.

Inventor: FAHRNSCHON WOLFGANG
IPC: C01B17/79
Filed: 1992-12-15
Abstract: SO3 prodn. by gas phase oxidn. of S with 02 and/or gas (I) contg. 02 at 400-600 deg.C is carried out in the presence of a low-alkali V205 catalyst (II) and an alkali-rich V205 catalyst (III), with V:alkali metal atomic ratio = (II) 5-100, (III) 0.2-2.0. The reaction mixt. is passed first through (II) and then through (III) or through mixt(s). of various fractions of (II) and (III).

Inventor: KRAIS RICHARD
IPC: B65G1/04
Filed: 1992-12-18
Abstract: A rack system for intermediate storage of bearing boards (3) occupied by moulded products consisting of concrete is described, which rack system comprises a rack and an apparatus for placing in and removing from storage in the vertical direction from the top or towards the top. Apart from an embodiment in which the bearing boards must have edge incisions or projections, the advantage of the preferred embodiment lies in the fact that customary bearing boards (3) can be used, the corners of which form the projections. The rack is a field of posts consisting of freely standing vertical posts (1) which are arranged in a grid corresponding to the format of the bearing boards (3) and on which supports (2) are fastened. A gripper (4) which can be moved above the rack can rotate the respective bearing board (3) horizontally by a small angle. In this travelling position, the gripper (4) can be lowered with the bearing board (3) between the posts and the supports (2). For the purpose of placing in storage, the bearing board (3) is turned back again and then rests with its corners on the supports (2). <IMAGE>

Title: Producing precision components by stamping stages
Inventor: STEPPER FRITZ
IPC: B21D43/09
Filed: 1993-01-15
Abstract: At least two material strips are fed in parallel to a mechanism which positively drives each strip at rates predetermined by a feed unit. The strips thus synchronised are fed in parallel to a common stamping tool within a stamping press. The resultant stampings are joined into a precision component.The driver mechanism incorporates at least two roll gaps (WA, WB) formed by roll pairs (8, 10; 9, 11) for the two material strips. At least two rolls (10, 11) are positively coupled in the strip feed direction. The roll diameters are chosen (or are adjustable) so that the desired feed rates are attained.Pref. the feed of the first strip is decoupled from the displacements imposed on the second strip by the stamping tool. The width of the roll gaps (WA, WB) and hence the pressure on the strips exerted by means of two adjustment mechanisms is independently variable.
